LOCOMOTIVE GRATE SHAKER.

Application filed February 6, 1923. Serial No. 617,285.

To (M w from it may concer'nf Be it known that I, GEORGE B. Asriwon'rn, of Amsterdam, in the county of Montgomery and State of New York, have invented a certain new and useful Improvement in Locomotive Grate Shakers, of which improvement the following is a specification.

The object of my invention is to provide an appliance of simple, compact, and inexpensive construction, which will be adapted to support a plurality of grate shaking levers, in proper position relatively to a locomotive firebox, prevent the dropping of fuel adjacent thereto from platform, and embody'suitable means for locking the levers in position.

The improvement claimed fully set forth: In the accompanying drawing: Figure 1 is a side view, in elevation, of a grate shaking appliance embodying my invention, attached in operative position to the back head of a locomotive boiler firebox; Fig. 2, a rear view, in elevation;

is hereinafter verse section, on the axial line of the fulcrum pin; and, Figs. 5, 6 and 7, detail views of one of the locking members.

In the practice of my invention, referring descriptively to e the specific embodiment thereof which is an integral casting. the top portion of which is rearwardly and downwardly inclined, on which are formed a top flange, 1, and side flanges, 1 through which it is secured, by bolts, 2, to the back'head, A, of a locomotive firebox. When so secured, the support covers an opening in the firing deck or floor, C, of the locomotive, in which it is fitted, and through which the grate shaking levers, presently to be described, extend downwardly to connections with the grate bars of the firebox. A plurality of parallel slots, 1 is formed in the top portion of the support, and lugs, 1?, are alsocast upon it. Bottom flanges, 1 on the sides and back of the support, extend below and around the opening in the firing deck in which itis fitted, and vertical ribs, 1, areinterposed between the slots, 1

A transversely extending fulcrum pin, 8, is fitted in the side portions of the support,

the firing. deck or ,7, pivoted to the lugs, each of said members Fig.3, a plan view, partly in section; Fig. 4, a vertical transherein exemplified, I provide a support, 1, which is in the form of an. open-bottomed casing, preferably as shown,

I anda plurality of grate shaking levers, 4c,

extend through the slots, 1 of the support, and are journalled to be oscillated, independently one of anothenon the fulcrum pin. The lower arms of the grate shakinglevers are coupled, by links or connecting rods, 5, to separate sets of the grate bars (not shown) in the ordinary manner, and the shaking levers are rocked, as from time to time required, by shaking bars, adapted to be engaged with their upper ends.

The grate shaking levers, 41, are held in their normal stationary positions, when not desired to be operated, by locking members, 1, of the support, 1, having a central recess, 7 adapted to engage one of the shaking levers, and lateral extensions, 7 ,which cover, and completely close, the spaces between the front andrear sides of said lever and'the endsof the slot, 1 of the support, 7 through which it passes. The locking members thereby present, with the top portion of the support, 1, a practically unbroken surface, down which any. fuel that may be dropped in firing, will fall to the firing deck, 30 and not drop through it. i

The operation of any ofthe shaking levers that may be desired, is efiected by swinging the locking member thereof upon its pivot in the support and thereby disengaging the, lever, which may then be rocked, either manually or by the application of power, in the ordinary manner. When the operation is completed, the shaking lever is returned to its normal middle position, shown in the drawing, and its locking member is swung down pn its pivot and engaged with it. H v i I am aware that looking members, pivotally connected to asupport, and adapted 0.70.19 7 engage shaking levers, are disclosed in Lettors Patent prior to my invention. and such appliances, broadly, I therefore disclaim.

I claim as myinvention and desire to secure by Letters Patent! 1. In a grate shaking appliance, the combination of a supporting casing, having a. plurality ofslots in its topportion; a. fulcrum pin, fitted transversely in said casing; grate levers, each journalled on saidpimand 105 extending through a casing slot; and locking members, each pivoted to the casing and adapted to engage a grate shaking lever and i i cover the spaces between the front and rear sides of said lever and the ends of the slot through which it passes.

2. In a grate shaking appliance, the'eombination of a supporting casing, having a plurality of slots in its top portion; a fulcruni pin, fitted transversely in said casing; grate levers, each journalledon said pin, and extending through a casing slot; and locking members, each pivoted to the easing and having a central recess adapted to engage a grate shaking lever and lateral extensions, substantially covering I the spaces lever and the
